New Research Offers Tantalizing Clues as to Why Some Teenagers Taking Common Anti-Depressants May Become More Aggressive or Kill Themselves

Posted: January 1, 2006

Neuroscientists at the University of Texas at Austin found that juvenile hamsters given low doses of fluoxetine hydrochloride, which is sold in the United States as Prozac, became more aggressive on low doses of the drug.  Juveniles given high doses became somewhat less aggressive, but not as much as adult hamsters, who calmed down on both high and low doses. Doctoral student and lead author Kereshmeh Taravosh-Lahn, B.A., says the findings confirm that juvenile and adult brains are different.  Thus, she says, It is unwise to expect a drug to work the same in juveniles as in adults.

The research is published in the October Behavioral Neuroscience, which is published by the American Psychological Association (APA).

Kereshmeh works with Dr. Yvon Delville in the Behavioral Neuroendocrinology Lab.
